core: reset crypto key counters when the keys are initialized

This fixes --sec rdp --salted-checksum in combination with farm redirect.

The counters are implicitly set to 0 in rdp_new, but they also has to be reset
after redirects. Resetting the counters when the keys are reset seems like the
cleanest solution.
